Please does anyone have experience of stainless steel soil pipe? I would like to use this for an upstairs toilet, from the pan, through the wall, to the tee piece on the outside, which would be normal 110mm plastic. The rest would be normal plastic pipe.
The outside diameters of stainless pipe I can find are 114.3mm or 101.6mm. The standard plastic pipe has outside diameter of 110mm.
The reason is that the existing plastic soil pipe has been damaged within the wall by heat from an adjacent chimney. The walls are rough stone, about
2 feet thick.James
